GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 309,291, datedDecember16, 1884.

Application filed April 25, 1884.

To all whom it may concern:

Beit known that I, JACOB BRENZEL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Grain-Car Doors, ofwhich the following is a specification, to wit:

This invention relates to an improvement in grain-car doors; and itconsists in the peculiar construction and arrangement of the saine,substantially as will be hereinafter more fully described and claimed.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich- Figure l is a side elevation of part of a freight-car with mydoor in use, and Fig. 2 is a vertical section of the door.

A represents a freight-car of the usual or any desired construction,provided with a rod, c, secured to the outside of the car just below theroof. To this rod is suspended by rigid links b b the door B, which ismade to fit the doorway of the car, and is in its upper part formed withan opening, b', closed by auxiliary doors B', hinged to the main door,and secured when closed by a hasp and padlock, C, or other convenientfastening.

To the lower part of the door B is pivoted a T-bar, D, having twohorizontal and one vertical arm, which are long enough to overlap thedoor-frame, and are secured beneath projecting blocks D', fixed to thecar-body.

(No model.)

One of these blocks is provided with a suitable locking device forsecuring the bar, in this oase simply a hasp and padlock, d, as in thecase of the upper doors.

The operation of this door is obvious. Ihe upper doors, B', are openedto get out the most of the grain, and then the T-bar D is swung upon itspivot to release the main door, and* this being swung out at the bottomis slid along on the rod a till the doorway is clear.

The door is strong and convenient, and is firmly held when locked orsecured, while being very quickly shoved aside, as desired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a car-door fastening, a T-sliaped bar pivoted at its center uponthe door and oscillating thereon to engage blocks upon the body of thecar beside the door, substantially as shown and described.

2. The ear A, having rod a, and under-cut blocks D', in combination withthe door B, having the auxiliary doors B in its upper part, and providedwith the T-bar D, pivoted upon its lower part, all constructed andarranged to operate substantially as and for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.

JACOB BRENZEL.
